I'm not the only person that just clicks back onto the beta in order to hear the beautiful soundtrack, right? I mean it's freaking breathtaking, in my opinion anyway. Also a question: What, in your opinion is the most well designed enemy in the game? Be it intimidation factor or simply something you can't wait to fight? Has to be the Cabal for me, the idea of combating some relentless machine of war and grinding it into dust just appeals to me...that said I can't wait to fight the Vex as well, will be nice to see the different tactics each enemy faction requires/dish out.
The soundtrack is amazing and I hope when the game is released the soundtrack will be released on iTunes or even on a disk (I would so buy it), it is epic and beautiful. As for enemies, the cabal are definitely up there. Since bungie said they are like the Roman Empire from space which added up with their size and weaponry could make for some very interesting conflicts them. Also I like the mystery and lore of the vex as well and hope to explore their origins in the full game (even if it is through grimoire cards). Also time traveling robots (although very cliche) are kinda cool.
